Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed March 21, 1906. Serial No. 307,170.

To all whom it may concern Be it known that I, ELMER E. VILLIAMS, acitizen of the United States, residing at the city of New York, boroughof Brooklyn, Kings county, in the State of New York, have inventedcertain new and useful Improvements in Machines for Making and DrivingFasteners, of which the following is a full, clear, and exactspecification.

My invention relates to improvements in machinery for securing togetheror uniting strips of wood or analogous material, and the same has forits object more particularly to provide a simple, eflicient and reliablemachine for making the ends of boxes and similar structures.

Further said invention has for its object to provide a machine in whichthe material of which the fastening devices are made is automaticallyfed into the machine in the form of a strip or band; the end of saidstrip or band severed therefrom in sections of predetermined andappropriate length, and the severed sections then driven into theopposing or adjoining edges of the wooden strips or material to beunited.

To the attainment of the aforesaid objects and ends my inventionconsists in the novel details of construction, and in the combination,connection and arrangement of parts hereinafter more fully described andthen pointed out in the claims.

In the accompan ing drawings forming part of this specification, whereinlike numerals of reference indicate like parts, Figure 1 is a front viewshowing a machine made according to and embodying my invention: Fig. 2is an end view; Fig. 3 is an enlarged detail side view of the feedingand driving mechanism, seen at Fig. 2; Fig. 4c is an enlarged detailfront view, partly in section, of said feeding and driving mechanism;Fig. 5 is a detail horizontal section taken on the line 5-5 of Fig. 3;Fig. 6 is a detail vertical section taken on the line 66 of Fig. 5; Fig.7 is a detail horizontal section taken on the line 7-7 of Fig. 6; Fig. 8is a perspective view of a fastener; Fig. 9 is a perspective viewshowing one end of a fastener embedded in a strip of wood, and Fig. 10is a top or face view of a box end consisting of two pieces of woodunited by fasteners.

In said drawings 15 designates a frame comprising a base 16, upon theupper surface of which near its opposite endsare bolted verticalsupports 17, 17 secured together at their upper ends by a transverse baror stay 18, and 19, 19 denote longitudinal slots or recesses provided insaid verranged upon said pulley by means of a1 treadle 2 1 andintermediatemechanism 25. Upon the outer ends of said driving shaft 21are fixed small gear wheels 26, 26 which mesh with the larger gearwheels 27, 27 fixed upon the ends of a shaft 28 which is mount.

ed in front of the main driving shaft 21 in suitable bearings in thesupports 17, 17.

Arranged and working within the supports 17 17 is a vertically-movablecrosshead 29 provided at its ends with oppositely projecting flanges 30,30 which serve to guide the ends of said cross-head 29 upon the supports17 17 and near the center of said cross-head are provided oppositelyprojecting members or arms 31, 31 which are disposed at right angles tothe crosshead 29 and provided along their lower edges with longitudinalrecesses 32, 32.

33,33 denote rods which are pivotally secured at their upper ends to theproiecting ends of the cross-head29 and at their lower ends to the gearwheels 27 27 on the shaft 28.

A short distance above the plate or table 20, and directly below thecross-head 29 is arranged a transverse support 3 1 which is rigidlysecured at its ends to the support 17 17 by screws or bolts 35 35. Nearthe center of said transverse support 34: are provided outwardlyprojecting members or arms 36 36, which are arranged substantially inalinement with the arms 31 31 on the cross-head 29, and provided ontheir upper surfaces with longitudinal recesses 37, 37. To the oppositeends of the plate or table 20 are secured brackets 38, 38, upon theouter ends of which are mounted reels 39, 39 each of which is, adaptedto receive a roll of metal strip or tape 40 preferably sharpened alongits lower edge, and corrugated transversely.

Partly upon the cross-head I 29, and

shown a machine incorporating only two mechanisms, but it will beobviousthat the invention is not limited to that number, as-

the number of such mechanisms may be increased or diminished at willwithin certain limitations, and as the said mechanisms are exactduplicates .of each other a detailedd-escription .of one will cover theother. Each of said mechanisms comprises a chuck or casing 41 having acover plate 42 provided at one sidewith a projecting arm 43. At the backof said casing 41 near its center is a rearwardly projecting lug 44adapted to rest upon the upper surface of the arm 36 on the transversesupport 34 and provided. with an aperture through which extends a bolt45 having its head 46 disposed within the longitudinal recess 37 in saidarm 36, and provided upon its upper threaded end with a wing-nut 47 bymeans of which said casing 41 may be secured to its adjusted po sitionupon the arm 36. The casing 1 is provided at its center with arectangular vertical recess 48 within which works a plunger 49 securedat its upper end to a block 50 adjustable in therecess 32 of the arm 31and adapted to be maintained within said recess 32 to its adjustedposition by a longitudinal plate :51 and screw 51*. The plunger 49 isprovided with a reduced lower "end 52, and to each side of said plunger49 within the casing 41 are provided jaws 53, 53 which are pivotallysupported at their upper ends upon screws 54, 54, and their lower endsprovided with inwardly projecting portions 55 which portions when incontact with each other produce a free portion intermediate said jawsadaptedto receive the end of the corrugated metal strip 40. The lowerends of said jaws 53 53 are held spring pressed against'each other bycoil springs 56, 56 arranged in chambers 57 57 at the lower end of thecasing 41, and adapted 'tobe. adjusted by'screws 58, 58 arranged in'theouter ends of said chambers.

At the lower left-hand side of the casing 41 is a shearing plate '59which is secured thereto by screws 60 60 passing through slots 61, 61and adapted for horizontal'adjustment by means of a screw 62 extendinginto said casing and contacting with the rear edge of said plate 59. Theinner edge of said plate 59 is arranged substantially ,on a line withthe inner edge of the left-hand jaw 53. In the right-hand lower side ofthe casing 41 is a horizontal-recess .63 within works a reciprocatingknife 64 having an inner scarfed end adapted to coiiperate with thefront edge of the plate 59 to sever the ends of the metal strip 40. Thereciprocation of said knife 64 is efiected through the medium of abell-crank lever 64? which is pivotally secured to the arm 43 of thechuck or casing cover 42', and has the end of its vertical memberpivotally secured to the projecting portion of the knife 64, and the endof its horizontal member pivotally secured to the lower end of a rod 65which has its upper portion loosely disposed within the adjustable block50 on the arm 31, which block also carries the plunger 49.

65, 65 denote stops adjustably secured upon the rod 65 above and belowthe projecting portion of the block 50, in order to permit thecross-head 29 and arm 31 to move up and down to a certain extent withoutactuating said rod 65.

At the lower edge of the casing 41 is secured a laterally projectingplate 66. Near the front edge of said plate 66 are arranged two feedrollers 67, 68. The roller 67 is smooth and is supported on'a slidinghearing 69 which is yieldingly maintained on said plate 66 by means of aspring 70 arranged in a chamber in the under side of said plate 66 whichbears at one end against said bearing 69, and at its other end againstan adjusting screw 71. The roller 68 is corrugated and providedwith abevel gear 72 which jointly revolve upon a short shaft or stud 73secured upon the plate 66, and at the side of said corrugated roller issecured a bifurcated bearing '74 in which is supported a shaft-75 havingfixed at its inner end a bevel gear Wheel 76 meshing with the bevel gearwheel 72 on the roller 68.

77 denotes a ratchet wheel which is fixed upon the shaft 75, and besidesaid ratchet wheel 77 is loosely mounted at its inner end an arm 78which is provided near its outer end with a spring pressed detent 79adapted to engage the ratchet wheel 7 7 I 8O denotes a rod which ispivotally secured at its lower end to the arm 7 8 and has its upperportion loosely disposed within the adjustable block 81 working in therecess 32 'of the'arm 31.

82 82 denote stops adjustabl-y secured upon the rod 80 above and belowthe block 81, so as to allow the cross-head 29, and arm 31 a limitedmovement in both directions without actuating the rod 80. The block .81is adapted for securement toits adjusted position upon the arm 31 by theplate .51'and screws 51 Upon the inner edge of the plate 66 adj acentto'the'feed roller67 issecured a bearing 83 in which is supported a rod84 having a head 85 at its inner end held against the by a spring 86disposed upon said rod intermediate its bearing and the head 85, and atthe outer end of said rod is a pin 87 which serves to limit the inwardmovement of said rod St.

Upon the front plate d2 of the chuck or casing ll directly above thepoint where the metal strip l0 enters the same is secured an adjustablebearing 88 in which is mounted a guide roller S9 adapted to contact withthe upper edge of the strip 40 and guide the same properly into thechuck or casing 11.

'lhe rperation of the machine is as fol- The strips of wood are placedside by r with their edges closely together upon the table and arrangedto be fed into the machine from its opposite sides. The machine is thenset in motion by throwing the clutch 23 into engagement with itscooperatparts on the pulley 29 As soon as this has been done the shaft21 and gear wheels 26, 26 will be caused to rotate and communicatemotion to the gear wheels 2'? 27, actuate the lOC s 33, 33, and causethe crosshead 29 to ascend and assume the position shown at Fig. 1. Asthe cross head 29 ascends it carries upward with it the plungers 4:9,as), and later in its movement first the rod 80 and then the rod 65.During the forepart of this upward movement the rod 80 lifts the arm 7 8and causes the detent 29 to partially rotate the shaft 75 and bevel gearwheel 76, and communicate a rotary movement to the corrugated feedroller 63 through the bevel gear wheel 72 thereon and thereby feedforward the end of the strip 40. During the remainder of the upwardmovement of the cross-head 29, and after the end of the strip :10 hasbeen fed into the chuck or casing 11., and is held in position betweenthe aws 53, 53 therein, the rod will actuate the bell crank lever on andcause the same to move the knife 64 inward, and in so doing sever theend of the strip of metal 40 held intermediate the jaws 53, 53.Hereupon, as the shaft 28 and gear wheels 27, 27 continue to rotate, therods 38, 33 will cause the cross head 29 to descend and force theplungers as 49 downward into the casings 41, 41 and in descending thelower reduced ends 52, 52 thereof will be brought to bear upon the upperedges of the fastening devices 90, 90 (which have now been formed, andare held between the aws 53, downward and into the abutting edges of theboards 91, 91 to be joined. The boards are thence fed forward and withthe next upward movement of the cross-head 29 the operation abovedescribed will be repeated, and continue until the clutch 23 isreleased, and the machine thrown out of operation.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:
